A NZ briefing note I saw a year or two ago mentioned that it is good to
have the wheel brake on because that improves the tyre's aquaplaning
capability. This lets the glider reach a lower speed before the wheel
finally sinks into the water.

Hydroplaning requires a water film over an impermeable surface (e.g.
roadway).

I saw RR's "baptism" from about a mile away on the ridge. It's not a
"landing". It's a "splashdown". The wheel, indeed the whole danged
airplane goes in the water, right now. Believe me when I say that
brakes or no brakes will make no difference. Having spoilers extended
can be be the difference between being airworthy the next day or
driving to the glider repair station.

Well hydroplanes (boats) manage to hydroplane over water, and the
tail dragger pilots who amuse themselves watersking their airplanes
(with brakes locked). Hydroplane is a perfectly good word to describe
that as far as I see. I think hydroplane (more ambitiously) and
aquaplane get used interchangeably for the wet road/tire situation. At
minimum energy speeds that gliders land I'm not brakes make much
difference, but I've also heard the suggestion to hold the brakes if
you have a separate wheel brake as in a Duo Discus, as it can help the
glider hydroplane/ski a little and help prevent the glider diving
under as much. And yes I've heard that from New Zealand. Anybody have
a spare Duo they want to test this with? Since it is unlikely to hurt
I'd be squeezing that brake handle in a Duo.
